Need to be able to measure viscosity, storage and loss modulus and tan delta, it should be able to control both applied strain or stress depending on measurement type, it needs to be able to control the normal force being applied and capable of dynamic mechanical analysis measurements utilizing 3 point bending, cantilever bending, tension and compression modes using controlled axial oscillations in ranges of -90 to 400 degrees Celsius. All accessories must be quick swappable.

Need parallel plate, cone and plate in 0, 20, and 40 degree angles; concentric cylinder and vane attachments, temperature control unit and an environmental temperature chamber (ETC) capable of withstanding -160 to 600 degrees C with heat rates up to 50 degrees/min. We will need torsion and geometry accessories kits to work with the

ETC.

Technical specifications.

For rheological application:

Section D: Efforts to Obtain Competition

Market research was performed reviewing Dynamic Small Business Search (DSBS) and System for Award Management (SAM).Gov databases using North American Industry Classification System (NAICS) Code 334516, Analytical Laboratory Instrument Manufacturing and keyword(s) Rheometer looking for companies that could provide (HR 30 Discovery Hybrid Rheometer. A review of small businesses to include 8(a), HUBZone, Service Disabled Veteran Owned Business, and Women Owned Small Business was conducted in search of a company that could provide HR 30 Discovery Hybrid Rheometer. In addition, GSA was also queried for any source that could provide HR 30 Discovery Hybrid Rheometer. The DSBS Query performed by the keyword "Rheometer" resulted in one (1) Veteran owned company, two (2) Asian pacific American, Other Minority owned and four (4) Small businesses. The GSA Advantage and GSA eLibrary queries resulted in zero (0) small businesses. Mandatory Sources such as Ability One were considered but did not meet this requirements.
